On the one hand, if they would merely flatly, clearly, unequivocably call for an end to terrorism and violence and assert that their only goal is true peace with Israel in a state alongside Israel and an honest attempt to stop terrorist attacks on Israel, that would be sufficient to be "reciprocity." On the other hand, if they cannot do these things, what is the point of negotiating with them? As per UN SC Res 242, the area is in legal limbo. Hypothetically, Israel can administer it until and unless all relevant parties can peacefully negotiate final status borders. In practice, if they won't stop attacking Israel, Israel will end up finishing the security fence and will simply wait them out. The wild card will be rockets/missiles. After what happened to Southern Lebanon in the war they started with Israel, I hope that the Palestinians don't start a similar foolish war that would only serve to devastate them further.
